WASHER.

SPECIFICATION forming part of Letters Patent No. 501,207, dated July 11,1893.

Application filed December 14, 1891. Serial No. 414,969- (No model.)

which it appertains to make and use the same.

This invention has general reference to improvements in axle washers;and it consists, essentially, in the novel and peculiar combination ofparts and details of construction, as

hereinafter first fully set forth and described and then pointed out inthe claim.

In the drawings already mentioned, which serve to illustrate thisinvention more fully, Figure 1 is a plan of an axle washer blankprevious to its being formed into a helix. Fig. 2 is an elevation of awasher coilready for the market. Fig. 3 is an end elevation of the same.7

Like parts are designated by corresponding letters of reference in allthe figures.

The object of this invention is the production of a helical coil to beused as axle Washers by cutting therefrom a portion sufficiently long toembrace the axle upon which the washer is to be used, such Washer-coilsconsistin g of a series of axle-washers having slits or cuts in theirexternal peripheryand adapted to be cut into individual washers. Toattain, this object, I construct this coil from strips of leather,raw-hide, vulcanized fiber, paper or paper pulp properly treated torender the same flexible, or any other suitable substance or material,A, of proper width and thickness, and produce along one side thereof aseries of incisions or excisions B, thus forming, as it were, a seriesof sections D, connected together by the roots E. These strips I thenform into a helical coil 0, Fig. 2, of

proper length so as to contain about twelve,

(more or less,) convolutions, winding them upon a suitable mandrel so asto permanently set the convolution s. This has the effect, whenincisions are made only of widening them and thereby produce lubricantretaining spaces so that a washer, though made of comparatively rigidmaterial or soft metal such as lead, and the like, will form a perfectand suitable washer for carriage and other vehicle axles. By producingthese incisions along the outer side of the washer blank I attain otherimportant results, viz: I can produce the widest strips and form theminto a coil to be used as washers, such wide washers not havingbeen madeby forming, as described but having to be made from hides of leather bycutting, it

being readily seen that my strips are'very narrow at the roots of theincisions and therefore readily formed into a coil. Washers of anydiameter may be made from these strips by cutting from the coil more orless than one convolution which will readily adapt themselves to theaxle upon which they are to be used.

' Vulcanized fiber, as heretofore mentioned, is an article ofmanufacture well known to the trade so that I do not believe itnecessary to describe its manufacture.

Having thus fully set forth my invention, I claim as new and desire tosecure to me by Letters Patent of the United States-- As an improvedarticle of manufacture, a series of axle-washers, formed into a helixhaving a number of convolutions and having slits or cuts in theirexternal peripheries and adapted to be cut into individual washers, asand for the purpose described.

In testimony that l claim the foregoing as my invention I have heretoset my hand in the presence of two subscribing witnesses.

TIMOTHY GINGRAS.
